 Gateworks is a hardware company that designs and manufactures single board computers and radios that can be used for IoT systems, most typically Gateways and Edge devices. Gateworks can custom create sensors as well for high volume projects.

+Requirements
+
+1. Node / Device
+ 1. [http://www.sparklan.com/p2-products-detail.php?PKey=1d706in8fkBM1aogttf0QPj2j2xnNC4Ud8OmmRXWAPM&WLRS-591EVB%20%20Series SparkLAN WLRS-591EVB]
+ 1. Connect to desktop/laptop via !CuteCom terminal program 
+ 1. Set freq
+ 1. Mac join abp, etc
+1. Gateworks SBC
+ 1. Install Ubuntu Bionic (Ventana) [wiki:ventana/ubuntu Instructions]
+ 1. Insert RAK2247 card into adapter (Because the card by default does not support active low reset which is what the Gateworks SBC uses. Contact RAK to have a RAK2247 modified to use a active low reset)
+ 1. Software pieces:
+  1. Github rak_common_for_gateway https://github.com/RAKWireless/rak_common_for_gateway
+   1. {{{ git clone https://github.com/RAKWireless/rak_common_for_gateway}}}
+   1. This talks to the actual radio card. 
+   1. Careful to set config file global_conf.json for frequency, and gateway to local host for this example (or The Things Network (TTN) if not using azure)
+   1. /root/rak_common_for_gateway/lora/rak2247/packet_forwarder/lora_pkt_fwd/lora_pkt_fwd
+  1. .deb package lora-gateway-bridge (must be v3.3 or higher)(now called chirpstack because of licensing issues)
+   1. The bridge is required because the packet forwarder cannot talk to Azure direct. It only speaks Lora Protocol. Azure needs something like MQTT, etc. So the bridge converts from Lora to MQTT.
+   1. https://www.chirpstack.io 
+   1. Download here: https://artifacts.chirpstack.io/downloads/lora-gateway-bridge/
+   1. lora-gateway-bridge -c /etc/lora-gateway-bridge/lora-gateway-bridge.toml
+    1. This is used 
+    1. Config file must specify the proper device ID thats set in Azure cloud, however, I felt the bridge was not listening to my config file and picked the eth0 MAC address as the device ID, so then I created a device in the cloud to match this MAC. 
+1. Azure Cloud
+ 1. Use pre-done remote monitoring solution accelerator (https://docs.microsoft.com/en-us/azure/iot-accelerators/iot-accelerators-remote-monitoring-sample-walkthrough)
+  1. Must get shared key device string like example:
+   1. 
+{{{
+HostName=gateworksremotemonitor-s2pc7.azurewebsites.net;DeviceId=GateworksTest1;SharedAccessKey=R9hjZNOvtfferesrsHzFGScSgc3EUxc004pjMg=
+}}}
+   1. Must create a device with a specific device ID. This device ID must be used by the MQTT lora-gateway-bridge
+
+=== Steps to take
+
+1. Make sure node is up and running and connected to with terminal program on laptop/desktop
+1. Start SBC and make sure packet forward is running first
+1. Then start the gateway bridge
+1. Then check for connected device on Azure
+1. Send packet from node and view on Azure
